` -This invention pertains" toan improved and novel tire chain snap -lock fastener, and

while this particular construction of fastener .f

' `Vthereof. s

In 'the embodiment of my invention as 55 is adaptedforgvarious purposes it is vespefy cially designed foriise in connecting and safely securing non-skid chains suchV asare commonly appli .hicles.

`lThe-main objectio'f theinvention is 'to proh10 vide a simple, durable, economical vand eiiitcientgmeansl for securing andflocking .tire

chainsaround the tire, when the chains'shall have been/appliedl to the tire.' v

f Further objects ofthe invention arejto :so

construct the chain locking' and .securing` means that it will includemeans for taking up slack -in theV chains' thereby insuring a Yneater. and Vmore accurate iittingofthe tireV j 'chains around thetire, and'A preventing too' ymuch looseness and swinging movement of the chains, and provides locking means which willpreve'nt any accidental disengagement of the chains from the fastening device, thereby -maintaining the chains'in their proper posi'-y evenwhen the' tion'with relation to the tire,

chains-are Vsubjected to exceedingly rough usage.

The

may appear'.

` nation of the several parts hereinafter vmore fully described, illustrated by the accompanyingl drawings and particularly pointed outin the claims appended hereto, it being understood that slight changes in the precise form, f proportions and minor ldetails of'construction 'may be resorted to' without departing from.' the spirit or sacrificing anyfof the advan` of tages vof the invention. In the accompanying drawings forming a part vof this specification itwill be seen that:

Figure l is a sideele'vation of the improved means embodyingl my invention. Figure 2 is a transverse section taken in the plane of the vdotted lines 22, Fig. l.

Figure Sis a side elevation of a slightly modified formi offfastening means showing it in its locked condition.

v Figure lis a sideelevation of the device foregoing and such other'objectsias'!r are accomplished by the ,confr` 30 struction, arrangement, location and coinbi,V 6 adapted t0 bef enggedandheld within the ,infi'ts locked 'positionwith itsrearY end por# 'tion :resting within the notch orrecess 1 3 j shown' inA 3, showing its locking inember' L in theunlocked position, and

Figures Band 6 represent vchet'ail views" illustrated, it willbe seen` by reference'to Fig; l? of the drawings thatV theznumeral ly ably of'rectangular shapein cross-section, as clearly shown in Fig. 2, and centrally formed i near [itsfrear end portion vis an'open'ing 2 adapted for ltherece'ption of the link of a chain or va rivet, whileat itsforward end por-v v '65 tion it is providedwith a notched opening 3 for the reception ofl one or more' of the end links ofthe tire chain orportion ofthe chain,Fand/intermediate,its ends is rigidly secured in any'suitable or desirable manner, I,- preferably riveted to eachl side face thereof and extending slightly yaboveits upper kface isa yoke member 4L formed from a metallic plate Iandbent intofthe formatiomsuch as shown Yin Fig. 2, yfor `the reception., of the locking member 5,'between its upper Ifaceand thefinnerface off thefmember 4f, saidlocking member lvbeing formed at its rear end with a downwardly and outwardly extended portion 'thejliook bodyv 19is' provided with a plurality of notched recesses 10, adapted to secure and retain. oneormore 'links ofja tirerc'hain in "90 each recess, thereby.adjustablyVv securing the hainrand insuringk a more'desirablerand ac "curate ittingl of the chain aroundthe tire,

said lio-ok body having secured thereto a yoker member 1l, and a locking member l1 2 j shown and 'its forward end portion .seating within v the notchedfportion 1 4 formed` in the hooky ber CJI

The deviceshown in Fig. 4 represents the device shown in Fig. 3 in its unlocked position, that is, the locking member l2 has beenv removed from, the recess 13 and slid rearwardly, thus leaving the plurality of notched unfasten the locking member, it is advisable to insert a screw driver, or-otheriiatinstrw,

ment under its rear portion a slight twist of the instrument being 'suicient `to lift the member and disengage it from the notch 13, then slide thememberrearwardly until it assumes the position shown in said Fig. 4. To lock the hook body Vsimply push the locking member forwardly until it is caused t0 assume the position shown in Fig. 3.

Itwill be understood that my improved fastening kand locking -means may be made ofl any suitable or desirable dimensions, and of any desirable material possessing therequired' strength and durability, and while onlytwo notchesy for the engagement. ofthe links of a tire-chain are shown in thedrawings,

Vit will be readily evident that any desirable number of chainzsecuring notches may be em# ployed, dependent" upon the purpose for which the-securing means is to be applied or intended.

By referenceto the detail views shown in Figs. 5 and 6, it will be seen that Fig. 5 shows a plan view of the steel plate locking means detached from thehook-bodyl with lateral eX# tensions l2 formed at one end thereof to prey vent saidrplate from being accidentally lostV y from the hook body when in unlocked condition,"and Fig. 6 shows a beveled portion 10 for the ready reception of a flat instrument or screw-.driver to unlock the spring plate whenrsai'dplate isgmade with a-V-lreavy plate spring.

' Having thus describedmy invention,what Ifclairn anddesireto-'secure by Letters Patent is: Y

l. A tire-'- chain4 snaplockv fastener, Y com prisi'ngl a hookbody, a fyokefmember rigidly secured to each side'v of said 'hook body` and extending above its'upper-f-ace, and a locking member having a downward andv outward extension at its rear end -iitted in a corresponding-recess formedin the upper face of the rear end portion of the hookbody and its forward end sea-tedin a horizontally disposed slot formedl in; the forward; end' por# tion ofsaid hook body.

2l Ati-re chain fastener of the character described, comprising ajh'ook body, a metallic yoke memberA riveted to eachl side face of the hookfb'ody and' eXtending abovethe upper face of the hookbody, and a locking member seated' on the upper facel of said hook body and slidingly disposedbetween' the'hook and Y hookbody andthe at its rear end adapted to be fitted in a corre-` sponding recess formed in the hook body with its front end fitted in a horizontally disposed slot formed in the front end portionl of the hookvbody.

A-fastenerof the-character described, comprising a hook body having a plurality of notchesformed .therein for,A the reception of chain links, a yoke member fixedly secured to each side face' cfgthe hook body and extending above the upper face of the hook body, and-:asteel'spninjg :plate locking member slidingly disposed between the upper face ofthe inner `face of the yoke, the

rear end portion of the locking-member Ibeing fitted in a recess formed in the'rear end" portion ofthe hook body and the front end portion ofl-the locking member tittedin -a horizontally disposed'recess formed in the forward portion of lsaid hook body.

a. A fastening device of thecharacter described, comprising a hook body formed-:with a down-ward'rand'inwardlyV disposed recess formed in-its upper face andIv a horizontal-ly disposedrecess formed in its frontend portion,a yoke rigidly secured tothe hook-body, a locking memberslidingly disposed between theupper face of the-hook body and said-yoke, the rear endvportion of the locking `member being adapted to be fitted in therecess formed in the upper face of' thehook body andthe front end lportion adapted to be' fitted in the recess formed in thefront end-portion ofsaid -f l hook body.
